呼叫 getDrawingCache（）你的图像视图。这将返回视图的缓存位图。这里阅读文档。

Call getDrawingCache() on your image view. This returns the cache bitmap of the view. Read documentation here.

保存位图PNG，创建邮件，并附加和发送。

Save the bitmap as PNG, create a mail and attach and send.

Bitmap bmp = imgView.getDrawingCache();
FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_WORLD_READABLE);
bmp.compress(Bitmap.CompressFormat.PNG, 0, fos);
fos.close();
